V NUT-LOCK.

To all whom it may concern:

Be it known that I, DANIEL B. HANLON, a citizen of the United States, and a resident of New Liberty, in the county of Owen and State of Kentucky, have invented a new and Improved Nut-Lock, of which the following is a full, clear, and exact description.

This invention relates particularly to improvements in locking devices for nuts on vehicle axle skeins, an object being to provide a nut lock that may be readily and a quickly adjusted for locking the nut in position and as readily detached when it is desired to remove a wheel from an axle.

I will describe a nutlock embodying my invention, and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings forming a part-of this s ecification, in which similar characters of. re erence indicate corresponding partsin all the figures.

Figure 1 is a front view of a thimble skein and a nut, with a nut lock embodying my invention in connection therewith; Fig; 2 is a sectional view thereof; and Fig. 3 is a perspective view of the locking pin. 7

Referring to the drawings, 1 designates an axle skein having the usual reduced portion 2 provided with a screw thread for receiving the nut 3. The said reduced portion 2 is provided with a channel 4 and the nut is provided with a channel 5. When these channels f and 5 are in alinement, a longitudinal perforation is provided for receiving a locking pin 6 provided at its outer end with a finger piece 7. Adjacent to the finger piece 7 the locking pin is provided with a tongue 8 designed to engage in a spring clip 9 attached Specification of Letters Patent. Application filed November 20, 1906.

to the nut, as here shown, by means of a x The spring clip is curved downward over the -outer face of the nut 3 and is chambered at its central portion, as indicated at 11, to

receive the part 8 carried by the locking pin.

In the operation, after placing the nut on the skein the key is to be inserted and turned to engage the tongue 8 in the chamber 11 in the clip 9, and as said pin engages in the two channels 4 and 5, it is obvious that the nut will be held from turning. To release the nut it is only necessary to give a turn to the pin, releasing the tongue from the clip and withdrawing the pin. i

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

In a nut lock, the combination with an axle having a screw threaded portion provided with a longitudinal groove adapted to register with the groove of the axle, and co-acting therewith to form a recess, a pin extendlng with a longitudinal groove, of a nut provided 7 into the recess, and provided with a lateral tongue for engaging the face of the nut, and a spring clip secured to the nut and extending over the outer face thereof and provided with a chambered portion for receiving the tongue whereby to lock the pin in place.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DANIEL B. HANLON.
